I recently added another nvme drive to run a mirrored cache pool, since then I haven't been able to install any docker images to it. Whenever I try and install one they end up getting stuck like this:

 

 

and then whole server hangs until I do a hard shutdown.

 

I had the same issue when I was using a single cache drive on btrfs, switching to xfs seemed to fix it, but that isn't an option with a cache pool.

 

Has anyone else had a similar issue?

Weird issue, can you try using a different device for cache, any other SSD or even a spinner just for testing?

Hey thanks for the reply, I found a spare ssd for testing, I just tried installing a couple different dockers but I'm still having the issue described above. I tried searching to see if anyone else has had a similar problem but the only posts I found were about dns issues with docker pulls, I ended up changing my dns to cloudflare 1.1.1.1 & 1.0.0.1 but that didn't seem to change anything.

Have you tried as of yet deleting the docker.img file?

You're getting a general protection error, same as before:

We now know is not related to the cache devices, so most likely related to your hardware, looks for a bios update and/or use different hardware if you can.
